LOOM PATTERN-CHAIN.

Specification of Letters Patent.

Patented July '2', 1914..

To all whom it may concern Be it known that I, JOSEPH KAY, a subject of the King of Great Britain, and resi-- dent of 39 Fairbank street, Windhill, Shipley, in the county of York, England, have invented a new and useful Improvement in Loom Pattern-Chains, of which the following description, which has reference to the of the loom mechanism for the varied purposes for which said mechanisms may be employed, and my said invention relates more particularly to that type or class of said devices which are produced of sheet metal.

The object of my invention is the production of said pattern chains of such a charactor as will enable the upper surface and side walls thereof to conform to the shape of the ordinary wood lags at present in use, and yet be light and firm and afford ready means for the fixing in position thereon or the removal therefrom of the raised surfaces or pegs for purposes wellknown, while the whole is rendered firm and durable to resist any of the forces that are brought to bear upon them throughout their several and varied operations. The parts of said devices which are subject to wear are of such a character as best to resist said wear and the several parts may be produced at comparatively little cost.

In order that my said invention may be readily understood I have hereunto appended a sheet of drawings illustrative thereof, to which, by figures and letters reference is made in the following description:

Figures 1 and 2 are respectively sectional side elevation and plan of parts constructed in accordance with my invention, the same being drawn to a reduced scale as compared with the other figures. Fig. 3 is an elevation showing the end of a lag and one projecting piece of peg mounted in posit-ion thereon. Fig. 4 is a plan of the parts shown by Fig. 3, with a certain holding device in position as when in use. Fig. 5 is a similar view to Fig. 4: but shows said holding device and the link in connection therewith in position as when freed for detachment. Fig. 6 illustrates a short portion of a strip of metal pierced or stamped with the necessary openings so that when subsequently bent into the shape desired my improved lag is produced. Fig. 7 is an end elevation of parts shown by Fig. 3 as seen in the direction indicated by the arrow a. Figs. 8 and 9 illustrate a part in detail which forms coupling means to secure one lag toanother. Fig. 10 is an end elevation of the parts shown by Fig. 5. Fig. 11 isa similar view to Fig. 3 but shows the parts inposition as illustrated by Figs. 5 and 10. Fig. 12 is a drawing in detail of a part hereinafter de' scribed. Figs. 13 and 14 are side and edge views of a strengthening part which is mounted in the interior of the bent strip hereinafter explained. 4 y

In carrying my invention into effect a strip 6 of sheet metal (see Fig. 6) of the necessary width is taken and perforated with the series of openings, hereinafter referred to, and it is then bent so that portions at the edges 12, Z2 will form side walls, while the part between will form the upper surface of .the lag in order to give said lag the outside contour of the present wooden lag, such contour being shown by Figs. 7 and 10. Perforated stay pieces 0 are fixed within or between said walls 6, b as by having their projecting parts 0 taking through openings 0 in the strip b there to be riveted (as will be understood) in order to support and fortify the side walls I), b as well as to act as guides or protecting means for preventing the said side walls of one lag entering the interior of one or other of its neighboring lags as the same are carried through their respective paths when in operation. Through the strip 6 are formed perforations cl in such positions thereon that when said strips Z) have their edges 7), b bent as above described, said openings d will fall on the edge of the lag to receive the bent ends f, f of the projecting piece f which I employ as the indicating means or pattern surface instead of the wooden or metal pegs customarily used in conjunction with the ordinary wooden lags. These projections f are formed of strips of metal preferably spring steel, so that by their bent ends f f taking within the openings 0? on the opposite edges of the lag Z2 they are held in position therein by their own recoil, causing the hooked ends (see Fig. 7) to enter and be retained with.-
